Abstract: The present invention is a jig system for precisely positioning the placement of multiple cuts such as in the placement of dovetail or box joints cut in a wood panel. A row of multi-use adjustable spacers controls the indexing of a workpiece and can be used with a stationary and/or a portable cutting tool. The movability of the spacers permits a workpiece to be cut on both sides of a guide bar fence thereby assuring that the first cut will always be made on the same side of a drawer and will be esthetically pleasing regardless of the width of the workpiece. Additionally, the adjustability of the spacers accommodates any desired cutting tool height, angle and/or size.
